for ciss, you can use camcontrol (in the base system) like that:

# camcontrol inquiry da0
pass0: <COMPAQ RAID 1  VOLUME OK> Fixed Direct Access SCSI-0 device
pass0: 135.168MB/s transfers

for amr, you can use the new port /usr/ports/sysutils/amrstat like that:

# amrstat
Logical volume 0        optimal (16.96 GB, RAID1)
Physical drive 0:0      online
Physical drive 0:1      online
